Lying here in tears just feeling like a total failure, my son is 2 and a half and he can be the sweetest thing but my god can be horrible. We are at my mums for a weekend, he went to sleep in his own bed but woke up crying at 2 asking to come in with me. I let him. I suddenly got woken up at 4am by him screaming to go downstairs, I told him to shh it's still night time everyone asleep and he just started shouting at the top of his lungs shut up mummy, go downstairs, it's morning. I told him it isn't morning, don't speak to me like that, come have a cuddle and we'll go back to sleep. Tried to give him a hug and he was just biting me, pulling my hair, pinching me just anyway he could hurt me he would. Screaming at me to shut up the entire time. I kept explaining everything is ok he's just woken up too early, and all he needs to do is stop hurting mummy and we can all go back to sleep, it's still night time that's all. The shouting and the hurting continued and he did a couple of shrill screams like as loud as he could. He woke the entire house up. My mum came in and took him in to the hallway and said you do not hurt your mummy like that, and you do not tell people to shut up, it is night time and we are all trying to sleep. Gave him options of his bed, my bed or her bed but said he must come and lie down in bed for an hour or so and if he's been good and not been mean again then we will go down stairs. He asked to come back in with me. Within 5 minutes he was shouting shut up at me because I said no we aren't going down stairs. I said I'm not talking to you if you're going to be mean to me, so I turned my back to him. Instantly sunk his teeth into my arm and grabbed two fistfuls of my hair as hard as he could. He wouldn't let go at all my mum heard me yelp in pain and came in and witnessed it all. She started saying that she had never seen a little boy be so nasty to his mummy and I just burst into tears. She's taken him into her room and he's not shouting at her yet but I can hear demanding things and refusing to get in bed. I can't believe how upset I am by it. What on Earth have I done wrong and how do I fix it. Shut up is a relatively new phase of his but he just isn't listening to us when we say he can't say it but this behaviour on this level has really shaken me up
